SPRINKLER.

in the county of San Diego, jstate oifflali fornia, have invented a -new andjn$eful which the r n winga speci Sprinkler, of fication.

The device used primarily but;,.not exclusively, as a lawn and garden sprinkler, and the invlen; tion aims to provide a v simple structure'- which WlllthlOV a spray -in any desired rection, Without wetting the operaton Another object of the invention is topmvide a device of the kind mentioned which will prevent a waste of water, and confine the sprinkling to the area which needs ,jto be sprinkled, "the construction" being such;

that, by shaping the slots. properly, oddly shaped pieces of groundmay- .be watered without waste.

' It is within the, province of thedisclosurei to improve generally and to enhance the utility of devices of that t pe to'jwhich thebody 12 and has an external thread 16 copresent invention appertains.

With the above and other objectsinview, If which .will appear asthe description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that,

within the scopeof what is claimed, changes. in the precise-embod ment. shown can be made without departing from the spirit of the invention; 7, v

In the accompanying drawings Figure 1 shows in front .'elevation',': adevice constructed in accordance with the invention; Fig. 2 is a side elevation; Fig. 3 is a longitudinal section on the line 3-3 of Fig. 1; Fig. 4 is a bottom plan; and 5 is a cross section showing a modification. In carrying out the invention as disclosed in Figs. 1, 2, 3 and 4, there is provided a head 1 supplied at its lower end with a ball 2 having achamber 3. In the side of the head 1 slots 4, 5 and 6 are formed. These slots may be constructed variously, without jeopardizing the utility of the invention. Preferably, the slots 4 and 6 slant toward'each other, at an acute angle to the axis of the head 1, whereas the slot 5 is disposed at right angles to the axis of the head.

t'udinally of the .head and forms a com- .munication.-;=betwen the chamber 3 and the slot 4. A smaller passage 8 forms a communication between the chamber 3 and'the slot 5. A still smaller passage 9 establishes communication between the chamber 3 and vthe slot 6;; The passages 7,8 and 9 preferably are disposed in alinement as shown 1n Fig. 4, the slot 5. being cut into the head 1 'mor'e' dieeply than is the slot 6, and the slot 4 be1ng cut into the head ljmore deeply than ..$j. ,the s 1ot"5 in order that the slots may comm nicatewith'th'e respective passages 7, and .9. which, as ihereinbefore explained are locatedi in alinement, one behind the otheni-The rear walls 'of the slots 4, 5 and 6 may 'be;;straight, as shown at 10.

h numeral 12- marks a tubular body provide'dat one end with an opening 18 and avi'n'g 'a-I flange 11 about the opening. The

head 1 passes outwardly through the open ing 18, the ball 2 engaging the inner surface ofthe, flange 11. The tubular body 12 preferably 1s milled externally, so that it "Ina be rotated readily.

tubular foot 15 extends within the it e body. The foot 15 is provided with an internalthread' 17 adapted to engage the coupllng' on the end of a hose, or any other In practical operation t e head 11 has a swiveled movement in the o ening 18 of the body 12 but, by advancing t e foot 15" in the body 12, the all 2 of the head 1 will be clamped between the flange 11 and. the inner end of the foot, and thus, the head 1 may held with its axis at variousanglcs to the axis of the body 12 and the foot 15. It is obvious/that owing to the adjustment above mentioned, the water proceeding through "the slots: 4, 5 and 6 may project at different angles :with respect to the horizontal. I v f 1 If the device is held' in the hand, the operator will not be wet, because, the slots, 4,

the rear Walls of the slots 4, 5 and 6 are straight, as shown at 10. This construction is not insisted upon. Thus, in Fi 5, where the modification appears the wa lls 10 of the slot 4* are disposed at an acute angle to each other, the head being denoted by the numeral 1, and the numeral 7 marking the passage which leads to the slot 4. In a' device constructed as shown in Fig. 5, it is possible to water a lawn, from one corner, without wetting the walks which may extend along the sides of the lawn. In general, the slots may be shaped as desired, so as to confine the lateral discharge to any desired area.

Having thus described the invention, what is claimed is:-

1. A nozzle comprising a head having separate longitudinal outer and inner passages and an intermediate passage, the passages bein of different lengths, the head being provided with transverse slots opening in a common direction and communicating at their inner ends with the inner ends of the respective passages, the slots which communicate with the outer and inner (passages converging as they extend inwar y, and the slot which communicates with the intermediate passage being disposed atright angles to the axis of the head, the slots being spaced from each other longitudinally of the head.

2. A device of the class described constructed as set forth in claim 1, and further characterized by the fact that the passages are of different diameters, the head being provided with a single chamber wherewith the outer ends of all of the passages communicate.
